Yii Set .htaccess for direct access project (frontend) & admin(backend)

Step 1.

Options +FollowSymlinks
RewriteEngine On

# deal with admin first
RewriteCond %{REQUEST_URI} ^/(admin) <------
RewriteRule ^admin/assets/(.*)$ backend/web/assets/$1 [L]
RewriteRule ^admin/css/(.*)$ backend/web/css/$1 [L]

RewriteCond %{REQUEST_URI} !^/backend/web/(assets|css)/  <------
RewriteCond %{REQUEST_URI} ^/(admin)  <------
RewriteRule ^.*$ backend/web/index.php [L]


RewriteCond %{REQUEST_URI} ^/(assets|css)  <------
RewriteRule ^assets/(.*)$ frontend/web/assets/$1 [L]
RewriteRule ^css/(.*)$ frontend/web/css/$1 [L]

RewriteCond %{REQUEST_URI} !^/(frontend|backend)/web/(assets|css)/  <------
RewriteCond %{REQUEST_URI} !index.php
RewriteCond %{REQUEST_FILENAME} !-f [OR]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ frontend/web/index.php

Note : if you are trying in local server then replace ^/ with ^/project_name/ where you see arrow sign. Remove those arrow sign <------ after setup is done.

Step 2.

create file Request.php in

common\components

and put below code:

<?php

namespace common\components;

class Request extends \yii\web\Request

{

   public $web;

   public $adminUrl;

   public function getBaseUrl()

   {

       return str_replace($this->web, "", parent::getBaseUrl()) . $this->adminUrl;

   }

   /*

     If you don't have this function, the admin site will 404 if you leave off

     the trailing slash.

     E.g.:

     Wouldn't work:

     site.com/admin

     Would work:

     site.com/admin/

     Using this function, both will work.

    */

   public function resolvePathInfo()

   {

       if ($this->getUrl() === $this->adminUrl)

       {

           return "";

       } else

       {

           return parent::resolvePathInfo();

       }

   }

}

Step 3.  put code

Installing component. Write below code in frontend/config/main.php and backend/config/main.phpfiles respectively.

//frontend, under components array
'request'=>[
    'class' => 'common\components\Request',
    'web'=> '/frontend/web'
],
'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
],

// backend, under components array
'request'=>[
    'class' => 'common\components\Request',
    'web'=> '/backend/web',
    'adminUrl' => '/admin'
],
'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
],

For Short URL:-

add rules in url manager

         'rules' =>
            [
                'country-add'=>'country/create',

                 'country-view/<id:\d>' => 'country/view', 

           ]
